Experimental relationships between levels of corticosterone in plasma and feathers in a free-living bird
SUMMARY Integrated measures of corticosterone (CORT), such as from feathers (CORTf), have intuitive appeal because they incorporate both the duration and amplitude of glucocorticoid secretion. AnExpand

Measuring corticosterone in feathers: Strengths, limitations, and suggestions for the future.
The recently introduced technique of measuring corticosterone in feathers currently provides the longest-term measure of corticosterone in birds. This review examines the strengths, weaknesses, andExpand

Does Environmental Enrichment Reduce Stress? An Integrated Measure of Corticosterone from Feathers Provides a Novel Perspective
Enrichment is widely used as tool for managing fearfulness, undesirable behaviors, and stress in captive animals, and for studying exploration and personality. Inconsistencies in previous studies ofExpand

Relationships Between Winter and Spring Weather and Northern Goshawk (Accipiter Gentilis) Reproduction in Northern Nevada
—Ecological factors, such as weather, play important roles in raptor population dynamics. We used logistic and Poisson regression analyses to investigate relationships between late winter, spring,Expand

Feather corticosterone of a nestling seabird reveals consequences of sex-specific parental investment
Offspring of long-lived species should face costs of parental trade-offs that vary with overall energetic demands encountered by parents during breeding. If sex differences exist in how parents makeExpand

Effects of ectoparasites on seasonal variation in quality of nestling Tree Swallows (Tachycineta bicolor)
Reproductive success often declines with breeding date in diverse taxa, including temperate-nesting bird species. The date hypothesis predicts that seasonally deteriorating environmental qualityExpand

Seasonal rainfall at long-term migratory staging sites is associated with altered carry-over effects in a Palearctic-African migratory bird
BackgroundAn understanding of year-round habitat use is essential for determining how carry-over effects shape population dynamics in long-distance migratory songbirds. The recent discovery ofExpand

Use of LC–MS–MS as an alternative to currently available immunoassay methods to quantitate corticosterone in egg yolk and albumen
AbstractCorticosterone (CORT) is the dominant plasma glucocorticoid in birds. There has been increasing interest in the function of CORT in avian egg yolk and in the potential to use CORTExpand

Do wild-caught urban house sparrows show desensitized stress responses to a novel stressor?
ABSTRACT While urbanization exposes individuals to novel challenges, urban areas may also constitute stable environments in which seasonal fluctuations are buffered. Baseline and stress-inducedExpand

Light-level geolocators reveal covariation between winter plumage molt and phenology in a trans-Saharan migratory bird
Contingent individual performance can depend on the environment experienced at previous life-stages. Migratory birds are especially susceptible to such carry-over effects as they periodically travelExpand
